Key features​

FeatureDetail
DeterministicSame API calls + same data = same PDF bytes. No embedded timestamps, no random document IDs, no HashMap-order variance.
Zero dependenciesShips as a single JAR with no transitive dependencies. No iText, no PDFBox, no Bouncy Castle.
Java 17+Built for modern Java. AutoCloseable documents, clean method signatures, no legacy compat.
Maven CentralPublished to Maven Central. Works with Maven, Gradle, and any JVM build tool. No license key, no custom repo.
Compact APIThree core classes: PdfDocument, PdfPage, PdfFont. You can generate a PDF in 5 lines.
TestableByte-identical output means you can assertArrayEquals against a golden file or compare SHA-256 hashes.

Quick example​

import dev.offixa.pdfixa.PdfDocument;
import dev.offixa.pdfixa.PdfPage;
import java.io.FileOutputStream;

public class QuickStart {
    public static void main(String[] args) throws Exception {
        try (PdfDocument doc = new PdfDocument()) {
            PdfPage page = doc.addPage(595, 842);           // A4

            page.drawTextBox(72, 750, 450, 40, "Hello from PDFixa!");

            doc.writeTo(new FileOutputStream("output.pdf"));
        }
    }
}

PdfDocument → add pages → draw content → writeTo. That's it.

Run the same code twice — you get the same bytes. Why this matters →
